Trail Running Map

great pit stop while backpacking through the alpine lakes for flyfishing.

Your socks will get wet. Tons of streams on the way. A few waterfall streams that have slippery rocks. Hike felt like 12-13 miles.

This was done October 14, 2017. The trail getting to Mason lake was gorgeous, fall colors everywhere. 2 miles into the hike the view was spectacular, there were about 2 inches of snow. After Mason Lake I suggest you bring Microspikes, over 2 feet of snow on the trail. The trail was easy to find. We didn't make it to the summit of Mt Defiance. We decide on a group decision to stop here about 500ft before the summit. There weren't any boot path to lead us the way, It took us 7.5 hours of hiking. Over 11 miles out and back, gained over 3,200ft of elevation.

Great trail, it's more like 14 miles out and back. There are a few technical sections of rock fields which were difficult for our dog. It was very secluded; literally no one else was using that trail. Other groups were headed to Granite mountain. Weather was interesting, 40 degrees and raining, which was fine in the woods but once we got into the river basin there isn't much coverage. I can't wait to go back and stay the night in those super cool camp sites along the far side of Pratt Lake.

Nice hike some snow on the ground as you get close to mount defiance

I love this hike. Mason Lake is SUPERB in the summer. I loved swimming there. I went to Mt. Defiance when there was still just a little snow on the ground and the views were fun. Since it's combined with Mason Lake, this is a really worthy hike. I'd do it again in the summer and get an even earlier start and bring even more food for chilling at the lake. I think you can camp there too, which would be awesome.

9/27/2017 (Wednesday) - Sunny day with cool wind, clear view, 60-70F. For me, this is a trail with the best conditions in the I-90 corridor, broad, smooth, moderate to gentle grade, not many rocky and rooty sections. It's a "thoroughfare" leading to all major trailheads on the northern sides of I-90 and to the southern side of the Middle Fork Snoqualmie River. We just go 4 miles to the highest point before the fork right down to Pratt Lake and left to Island Lake. The trail is all inside the woods, and has only one opening of less than 10 yards, where, we can see Olallie Lake and Mt. Rainier to the south, but, while eating lunch there, we were harassed by several big birds with big heads. While trying to find the boot trail down to Olallie Lake, we can't find it. It's unclear and rarely used.

a lot of up and down along this trail. We did it backwards but it was a great hike.

Arrived at 7:20 AM with plenty of space to park, about 20 vehicles in the parking lot. Trail was great, ascended to Mason Lake quickly and saw plenty of campers. Continued on to Mt Defiance and reached the top fairly quickly. I was joined by about five or six other people in the twenty minutes I spent up there before I started to descend. I was surprised at the lack of people ascending past Mason Lake, but once I got back to Mason Lake I noticed much larger crowds. I took a dip in the chilly waters, which was refreshing, and then made my way back to the car. On the way back I passed a large number of people who I assume were going to Mason Lake, and once back to the parking lot (around 1pm) it was completely full with the spillout running way down the forest road. I enjoyed this trail but would recommend getting there around 8 AM to enjoy the trail in a little more peace.

Went up there today 08/25/2015, parked at Ira spring trailhead parking lot was almost full at 8:57am. Trail is very well marked till Mason Lake and once you reach at lake stay on the main trail and after half a mile you will see a signs directing towards Mount defiance. Last mile was steep but doable. Took 1 hour 40 minutes to Mason lake and 1 more hour to mount defiance. 2 hours to decent down to Parking lot. Used hiking poles to decent. Make sure bring plenty of water.
Best of luck

Hiked 8/12/17. This was my third time to the trail. First was up to Lake Mason; second we crawled over and under large trees blown down by winter storm for 3 miles just to trailhead and another 1.5 on the trail (total obstacle course); this time we went past lake up Mt Defiance. Defiance was challenging and wooded for part of it before exiting into a meadow that was filled with beautiful wild flowers. To reach the summit, the last ~150ft of gain was very steep.

People swimming in lake as we descended; nice campgrounds around lake area for backpackers. I only gave this trail 4 stars due to the crowds, but an awesome hike nevertheless!

This is a longer hike then suggested by this app. My fit bit was dead so I am not sure how much over but by pace I would say it's closer to 12.5. Like most Alpine hikes the hardest part is the hike out of the basin. Pratt is a nice lake but not awe inspiring I don't think I would do it again as a day hike but with other lakes nearby it would make a decent backpacking trip

Hiked 7/23/17 - BRING BUG SPRAY. We were blown away by how many cars were parked, but most were going to mason lake. Pretty busy all the way to the lake, not super hard hiking but makes you sweat. The last few miles to mount defiance were so beautiful, and minimal people. The last half mile is killer but totally worth it. The bugs were SO bad at the top, we rushed to take a few pictures and get out of there, they were even driving the dog nuts. Bugs at the lake were annoying but nothing compared to the peak. Overall super fun!

Hiked at night with flashlight to summit to watch sunrise. Total fog at sunrise and millions of biting flies on the top. Pretty coming back down though! Way too many day hikers coming up to Mason Lake.

Passed through this lake. And it's a great spot. I understand why this place is a popular destination to get to. Clear water, breezy, space for camping and daypacking, a good spot to rest between junctions. On sunny clear days it's definitely one that everyone should try to visit.

Amazing Trail to Mason Lake. With the exception of the gigantic swarm of mosquitos that won't stop bothering you (bring a repellant☺).

Great overnight! Worth the swim out to the log in the middle of the lake.

Pretty challenging hike. Loved the lake itself. Headed down another half mile to a lake as well and it was phenomenal!

Made it to the top of Mount Defiance but had to tread through quite a bit of snow. Trail is unsteady in a lot of areas but it's doable if you take caution.

Great hike, couple of icy/snow spots to be watchful, I did not have poles but navigating around and on them was easy, outside of those spots it is a beautiful hike.

Quiet day on the trail. Some snow but all easily passable. Rewarded with a beautiful lake at the end.

Didn't make it to mount defiance cuz the snow is pretty unstable and I fell in a few times. I did go to lake mason and then came back and up the other side of the lake - awesome view! I did not want to leave : )

This was a great hike! There were a lot of potholes getting to the entrance so drive slow. Once you get on the trail the beginning had lots of fallen branches and debris. Past that the trail goes straight up. Kicks your butt!! I didn't make it to the lake because it snowed a couple days ago and it was too thick. Hope to go back in a few weeks when everything has melted. Made it 2.5 miles before turning around. Went up twice just for cardio and it was 9.8 miles round trip.

You'll hit snow a mile or so into the hike. By mile 3 it is deep and you start to fall through. Tried to take the Talapus cutoff to Olallie... cutoff trail is very deep in snow, and the creeks are running high with many crossings are sketchy. FYI there is no bridge when the cutoff trail hits the creek. You have to walk up or down the river to find a place to cross. We lost the trail here. Be careful.

The trail is like others have said, very beautiful. So many waterfalls the first 3/4th of the hike. Then you get to enjoy the deadness of the snow. So breath taking. The lake itself is small and the look out point is meh. Toward the very end the trail is easily lost in the snow and gets quite narrow. I went on a Monday and only saw 2 people which was nice.

The trail itself is spectacular..... I really lost count on how many small streams and little waterfalls there were along the way. The lake was pretty disappointing. There are just far more scenic lakes in the area. I have made the approach from three different ways: ira spring, Talapus, and now Pratt/granite... in my personal opinion, The dissent into the prat lake basin.. is just not worth The climb out… (800 ft+ down after 7 or 8 miles and 2500+ heading up) I would recommend the trail though I will never go back… trail conditions: muddy, wet, fun, and so far, no blow downs. Just to be clear… Pratt Lake Trail is not the same as the Talapus /ollalie trail.

Never have a stopped so frequently on a hike just to take pictures. You'll enjoy awesome views the entire length of the trail. The trail is pretty easy for the first 4 miles. However once you pass the sign that says Mt. Defiance you can expect one FIERCLY DEFIANT mountain! The last mile was grueling and the turn to the summit was so subtle I almost missed it (thank you AllTrails map!). One of the single best hikes I've done to date. Loved it.

Mount defiance is a beast. It took us 6 hours round trip (we ventured off to another lake for 30 minutes). From Mason lake it is at least another hour to an hour and half. Hard but worth it. Going to take my dad up it in the spring. It keeps going up. You have to follow the trail and just keep going. You will reach the top.
